All patients referred with a clinical and radiological diagnosis of SAH will be considered suitable on satisfying the inclusion and exclusion criteria.
To be included in the study:
- Male or female subjects, aged 18-65 years, in whom the admitting neurosurgeon has confirmatory evidence of an aneurysm, either by CT angiography, MR angiography or DSA.
- Any clinical grade accepted provided a reasonable prospect of survival.
- Delay to randomisation and initiation of trial medication, from the time of the presenting ictus, does not exceed 96 hours.
- Independent prior to the SAH.
- Informed consent given.
The presence of any of the following will preclude patient inclusion:
- Unsalvageable patients: fixed and dilated pupils after resuscitation, and/or a devastating scan, which precludes definitive therapy.
- Already taking statin therapy.
- Those taking warfarin type drugs.
- Pregnancy.
- Known significant renal or hepatic impairment.
- Suspected or known additional disease process, which threatens life expectancy.
- Known or strong suspicion of significant drug abuse, alcoholism, or those who are unlikely to be amenable to 6 month follow up.
